Abstract
The invention discloses a novel structure wrap seal gasket. The gasket comprises a seal belt, a rubber coating, a mental lamina and an asbestos seal plate,wherein the mental lamina is covered by the asbestos seal plate,and the asbestos seal plate and the mental lamina share the same shape. Both sides of the mental lamina are provided with rubber coatings, and the seal belt is mounted outside the rubber coatings of the mental lamina. The gasket is capable of effectively padding the leakage phenomena of sealing surface caused by bad sealing, and effectively sealing gas,oil, water and on the like. The gasket has the advantages of being good in rigidity, endurable in the high temperature above 400 DEG C, good in elasticity of compression by utilizing the seal plate as a liner, namely suitable for the special working environment of large machinery equipment, endurable in the high temperature and low temperature and high pressure and oil and water, and extremely good to prevent corrosion.
Description
Technical field
The present invention relates to a kind of cylinder pad, specifically a kind of coated sealing pad of new structure.
Background technology
Gasket seal, as long as be it is a kind of have the sealing spare part for being exactly where fluid for machinery, equipment, pipeline,
Using inside and outside, the material for sealing.Gasket seal is cleaved, punching press or sanction with metal or nonmetallic tabular material
The technique such as cut to make, for being tightly connected between pipeline, being tightly connected between the parts and parts of machinery equipment.By material
Metallic packing and nonmetallic gasket seal can be divided into.Metal has copper backing, stainless steel gasket, iron gasket, aluminium backing etc..
Nonmetallic has asbestos washer, non-asbestos pad, paper gasket, rubber sheet gasket etc..Gasket seal is played in metallic combination cylinder
Important effect, existing gasket seal poor rigidity, resistance to elevated temperatures is poor, and easy breakdown leakage is perishable.According to prior art
Deficiency, the present invention proposes another kind of solution.
The content of the invention
It is an object of the invention to provide a kind of coated sealing pad of new structure, to solve above-mentioned background technology in
The problem of proposition.
For achieving the above object, the present invention provides following technical scheme：
A kind of coated sealing pad of new structure, including band, rubber coating, sheet metal and asbestos seal plate, institute
State asbestos seal plate to be coated in the middle of sheet metal, asbestos seal plate is identical with sheet metal shape, and for rectangle, square or
Circle, the two sides of the sheet metal is equipped with rubber coating, and the rubber coating adopts fluorubber, nitrile rubber or neoprene rubber
Glue, the two sides of the sheet metal is additionally provided with band in rubber coating outside, and band is made using silicon rubber.
As further scheme of the invention：The thickness of the sheet metal is 0.22～0.30mm.
As further scheme of the invention：The thickness of the asbestos seal plate is 1.52～1.68mm.
As further scheme of the invention：The rubber coating thickness is 0.03～0.04mm.
As further scheme of the invention：The width of the band is 3.9～4.5mm, highly for 0.04～
0.09mm。
Compared with prior art, the invention has the beneficial effects as follows：The gasket seal effectively fills up sealing surface because once close
The bad caused leakage phenomenon of envelope, more effectively forms the sealing function to media such as vapour, oil, water, and good, resistance to rigidity
400 DEG C of high temperature above, are difficult breakdown leakage, and centre employs sealing plate and makees liner, make product have preferable compression resilience
Can, that is, particular job environmental demand of heavy mechanical equipment is adapted to, high temperature resistant, low temperature, high pressure, oil, water etc. and can have fabulous
Corrosion-resistant effect.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：1- bands, 2- rubber coatings, 3- sheet metals, 4- asbestos seal plates.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly and completely
Description, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.Based on this
Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Fig. 1 is referred to, in the embodiment of the present invention, a kind of coated sealing pad of new structure, including band 1, rubber
Gel coating 2, sheet metal 3 and asbestos seal plate 4, the asbestos seal plate 4 is coated in the middle of sheet metal 3, and the asbestos are close
Shrouding 4 is identical with the shape of sheet metal 3, and for rectangle, square or circular, and the thickness of the sheet metal 3 is 0.22～
0.30mm, the thickness of the asbestos seal plate 4 is 1.52～1.68mm, and the two sides of the sheet metal 3 is equipped with rubber coating
2, the thickness of the rubber coating 2 is 0.03～0.04mm, and the rubber coating 2 adopts fluorubber, nitrile rubber or neoprene,
The two sides of the sheet metal 3 is additionally provided with band 1 in the outside of rubber coating 2, and the band 1 is made using silicon rubber, institute
The width for stating band 1 is 3.9～4.5mm, is highly 0.04～0.09mm.
In sum, novel seal pad provided by the present invention is effectively filled up sealing surface and is drawn because once sealing is bad
The leakage phenomenon for rising, more effectively forms the sealing function to media such as vapour, oil, water, and good, resistance to more than 400 DEG C with rigidity
High temperature, is difficult breakdown leakage, and centre employs sealing plate and makees liner, makes product have preferable compression recovery performance, that is, adapt to
Particular job environmental demand of heavy mechanical equipment, high temperature resistant, low temperature, high pressure, oil, water etc. and can have fabulous corrosion-resistant work
With.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of spirit or essential attributes without departing substantially from the present invention, the present invention can be in other specific forms realized.Therefore, no matter
